Abstract

The durability of tools can by improved by the introduction and development of methods of surface hardening. The industry is already performing hardening by highly concentrated energy sources such as laser beams, plasma jets, electron beams. However, this kind of hardening cannot yet replace completely volume heat treatment in tool manufacturing. This is connected with the short time of the temperature action of the highly concentrated energy source, which leads to incomplete structural and phase transformations that determine the operational properties of tool materials. An important way for improving the tool hardening consists in the development of combined technological processes including volume and surface heat treatment. The present paper is devoted to this problem.
